This happens because the source package includes doctree pickles (in which parsed rST sources are cached) were generated by Python 2.X, and cannot be loaded by Python 3.X. Please ask upstream to exclude the doctrees/ subdirectory from their tarballs. Meanwhile please use the attached patch as a work-around.
So if I understand correctly the python-sphinx upstream bug entry, I don't have to ask upstream to remove the doctrees, sphinx will detect alone that it's not compatible.

It's still a bad idea for upstream to include them in the tarball:
- They take significant amount of space.
- They leak information about upstream's home directory layout; try this for example: $ strings docs/_build/doctrees/*.doctree | grep ^/User

Maybe more importantly, they are bad for us, because they are unauditable. Quoting <http://docs.python.org/2/library/pickle.html>: "The pickle module is not intended to be secure against erroneous or maliciously constructed data. Never unpickle data received from an untrusted or unauthenticated source."

Anyway, I made this pull request:
https://bitbucket.org/ubernostrum/django-registration/pull-request/34

Now a question about your patch:

 override_dh_auto_clean:
-       rm -rf docs/_build/html
+       rm -rf docs/_build/
        dh_auto_clean

 override_dh_auto_build:
        cd registration && /usr/bin/django-admin compilemessages
+       rm -rf docs/_build/doctrees/
        cd docs && $(MAKE) html
        dh_auto_build

Why do you have to remove docs/_build/doctrees/ again in override_dh_auto_build ? any dpkg-buildpackage call starts with "debian/rules clean" and thus docs/_build will already have been removed...

I don't believe one can assume that clean is always run before build. dpkg-buildpackage does that, because it has no way of knowing whether the package is in a clean state or not. But IMO the following is also a legitimate way to build a package:

$ dpkg-source -x foo_*.dsc
$ cd foo-*/
$ debian/rules build
$ fakeroot debian/rules binary
